Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or display that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or display.

The mite-killing dust collector in the related art comprises a shell, a dust cup and a suction motor, wherein the shell mainly comprises three parts, namely a base shell, a motor shell and a handle, the motor shell is connected to the rear end of the base shell, the base shell and the motor shell are approximately in a T-shaped arrangement, the handle is connected to the upper side of the motor shell, the dust cup is detachably connected to the middle of the base shell, and the suction motor is arranged in the motor shell. The bottom surface of the base shell is provided with a suction inlet, a rolling brush is arranged at the suction inlet, and when the bottom surface of the base shell is contacted with the surface to be cleaned, the rolling brush beats the surface to be cleaned and sucks dust mites into the dust cup through negative pressure suction provided by the suction motor.

However, since the suction motor is disposed at the rear of the mite-killing cleaner, and the weight of the suction motor is heavy, the center of gravity of the mite-killing cleaner is offset toward the rear end of the mite-killing cleaner, and the mite-killing cleaner is easy to tilt forward due to the backward movement of the center of gravity when moving, when moving the mite-killing cleaner, a user needs to push the mite-killing cleaner to move in the front-rear direction, and also needs to apply a downward force to the mite-killing cleaner, so that the user is hard to move the mite-killing cleaner. If the downward force is not applied to the mite-killing dust collector during movement, the mite-killing dust collector is easy to incline forwards due to the backward movement of the gravity center, and the bottom surface of the base shell cannot be well attached to the surface to be cleaned, so that the mite-killing dust collector cannot be smoothly pushed to move along the advancing direction.

In view of the above problems, the present application provides a dust cup assembly and a motor assembly are respectively disposed at two opposite sides of a running direction of the dust cup assembly and one or both of the motor assembly are disposed at an included angle with respect to a placement surface, and are communicated through an air duct pipe, so that a center of gravity of the dust cup assembly is located in a middle part of the dust cup assembly, and further, a front inclination of the dust cup assembly due to the center of gravity of the dust cup assembly being located at a rear end is avoided, and therefore, when a user uses the dust cup assembly, only a force is required to drive the dust cup assembly to move forward or backward, and the dust cup assembly is not required to be pressed down.

In order to concentrate the weight of the mite-killing cleaner toward the middle of the mite-killing cleaner and uniformly distribute the weight, the dust cup assembly 200 and the motor assembly 300 may be disposed at opposite sides of the traveling direction of the mite-killing cleaner, respectively, and one or both of the dust cup assembly 200 and the motor assembly 300 may be disposed at an angle with respect to the placement surface 120. When the axial direction of the cyclone 220 is inclined to the placement surface 120 or is perpendicular to the placement surface 120, the weight of the dust cup assembly 200 is more concentrated toward the middle of the mite-killing dust collector relative to the axial direction of the cyclone 220 and the placement surface 120. When the axial direction of the driving shaft of the motor 310 is inclined or perpendicular to the placement surface 120, the weight of the motor assembly 300 is concentrated more toward the middle of the acarid-killing cleaner with respect to the axial direction of the driving shaft of the motor 310 and the placement surface 120 being parallel to each other.

In this way, at least one of the axial direction of the cyclone 220 and the axial direction of the drive shaft of the motor 310 may be disposed at an angle to the placement surface 120.

In order to facilitate the communication between the motor installation cavity 110 and the dust cup 210, which are positioned at the opposite sides of the running direction of the mite-killing dust collector, an air duct pipe 400 is provided between the motor installation cavity 110 and the dust cup 210, so that when the motor 310 generates negative pressure in the motor installation cavity 110, the suction force can drive the gas to take away the dust mites on the surface to be cleaned into the dust cup 210, after cyclone separation by the cyclone 220, the dust mites are collected in the dust cup 210, and the gas continues to flow to the motor installation cavity 110 along the air duct pipe 400 under the action of the suction force, and finally is discharged out of the motor installation cavity 110.

The embodiment of the application provides a dust collector for removing mites, which comprises a shell 100, a dust cup assembly 200 and a motor assembly 300, wherein the shell 100 comprises a placing surface 120, the dust cup assembly 200 comprises a dust cup 210 and a cyclone barrel 220, the motor assembly 300 comprises a motor 310, a motor mounting cavity 110 is arranged for mounting the motor assembly 300, the placing surface 120 is arranged for contacting a surface to be cleaned, the motor 310 is arranged for providing suction force so that dust mites on the surface to be cleaned are sucked into the dust cup 210 along with gas, the cyclone barrel 220 is arranged for separating dust mites flowing along with the gas, the dust cup 210 is arranged for collecting the separated dust mites, the dust cup assembly 200 and the motor assembly 300 are arranged on two opposite sides of the running direction of the dust collector, at least one of the axial direction of the cyclone barrel 220 and the axial direction of a driving shaft of the motor 310 is directed towards the placing surface 120, the weight on two opposite sides of the running direction of the dust collector is concentrated towards the middle part of the dust collector, the dust collector is uniformly distributed, the dust mites collector is prevented from being deflected to one side, the dust collector is prevented from being sucked along with the gas, the dust collector is required to flow down along with the air duct 400 through the pressure of the motor at the rear end of the dust collector, the dust collector is arranged in the dust collector tube 400, the dust collector is connected with the dust collector tube 400 along the air duct, and the dust collector is arranged along the air duct 400, and the circulating through the dust collector is arranged to be connected with the dust collector tube 110. Therefore, the mite-killing dust collector provided by the embodiment of the application is more labor-saving to use.

That is, the bottom surface of the base 130 forms the placement surface 120, and the motor mounting part 140 and the dust cup 210 are respectively disposed at opposite sides of the base 130 along the traveling direction of the mite-killing cleaner, so that the motor assembly 300 and the dust cup assembly 200 are respectively disposed at opposite sides of the traveling direction of the mite-killing cleaner, and further the weight of the mite-killing cleaner is more uniformly distributed at opposite sides of the traveling direction of the mite-killing cleaner, thereby saving effort when a user pushes the mite-killing cleaner to move.

Wherein, the motor mounting part 140 and the dust collecting cup 210 can be arranged in parallel on the base 130, so that the whole appearance of the mite-killing dust collector is beautiful.

Referring to fig. 5, in one possible implementation, the mite-killing dust collector provided by the embodiment of the present application further includes a release valve assembly 500, wherein a first end of the release valve assembly 500 is communicated with the air duct 400, and a second end of the release valve assembly 500 is communicated with the outside of the base 130 and is configured to regulate the pressure in the air duct 400.

It should be appreciated that if the vacuum level in the air duct 400 is too high, the service life of the motor 310 is shortened, so that the air release valve assembly 500 needs to be controlled to adjust when the vacuum level in the air duct 400 is high, so that when the pressure in the air duct 400 is too high, the air release valve assembly 500 can be controlled to release part of air out of the air duct 400, thereby reducing the pressure in the air duct 400, and avoiding the influence on the service life of the motor 310 due to the excessive vacuum level in the air duct 400.

Referring to fig. 3, since the motor installation chamber 110 and the dust cup 210 are located at opposite sides of the traveling direction of the mite-killing cleaner and at least one of the axial direction of the cyclone 220 and the axial direction of the driving shaft of the motor 310 is perpendicular to the placement surface 120, in particular, the duct tube 400 includes a first tube segment 410, a second tube segment 420 and a third tube segment 430 which are sequentially communicated, the first tube segment 410 is communicated with the dust cup 210, and the third tube segment 430 is communicated with the motor installation chamber 110.

It should be noted that, because the space inside the base 130 is limited, in order to facilitate the connection of the air release valve assembly 500 to the air duct 400, the first end of the air release valve assembly 500 may be connected to the second pipe.

In one possible implementation, the first pipe segment 410 and the third pipe segment 430 are arc segments, the second pipe segment 420 is a straight segment, and the second pipe segment 420 is disposed at an angle to the traveling direction of the acarid cleaner.

It will be appreciated that the portions of the first tube segment 410 and the second tube segment 420 that are adjacent to each other, and the portions of the third tube segment 430 and the second tube segment 420 that are adjacent to each other, are curved, and the projection of the second tube segment 420 on the placement surface 120 may be perpendicular to the direction of travel of the acarid-killing cleaner, or inclined with respect to the direction of travel of the acarid-killing cleaner, so that the first tube segment 410, the second tube segment 420, and the third tube segment 430 are advantageously shaped, and the resistance of the gas when changing the flow direction is reduced, thereby reducing the flow resistance of the gas in the duct tube 400.

In some embodiments, the axis of the cyclone 220 and the axis of the drive shaft of the motor 310 are both angled with respect to the placement surface 120.

That is, the axial direction of the cyclone 220 and the axial direction of the driving shaft of the motor 310 may be perpendicular to the placement surface 120, or one of the axial direction of the cyclone 220 and the axial direction of the driving shaft of the motor 310 may be perpendicular to the placement surface 120, and the other may be inclined with respect to the placement surface 120, so that the weight of the motor assembly 300 and the dust cup assembly 200 may be more concentrated toward the middle of the mite-removing cleaner.

In one possible implementation, the axial direction of the cyclone 220 and the axial direction of the driving shaft of the motor 310 are perpendicular to the placement surface 120, the air outlet direction of the first pipe segment 410 is along the axial direction of the cyclone 220, and the air inlet direction of the third pipe segment 430 is along the axial direction of the driving shaft of the motor 310.

In the above arrangement, since the axial direction of the cyclone 220 and the axial direction of the driving shaft of the motor 310 are perpendicular to the placement surface 120, in order to communicate the dust cup 210 with the motor mounting cavity 110 by using the shorter air duct 400, the air outlet direction of the first pipe section 410 may be consistent with the axial direction of the cyclone 220, the extending direction of the second pipe section 420 may be parallel to the placement surface 120, and the air inlet direction of the third pipe section 430 may be consistent with the axial direction of the driving shaft of the motor 310, so that the U-shaped air duct 400 may be formed to communicate the dust cup 210 with the motor mounting cavity 110, thereby making the air flow more smooth with smaller resistance during flowing.

In one possible implementation, one of the axial direction of the cyclone 220 and the axial direction of the drive shaft of the motor 310 is perpendicular to the placement surface 120, and the other is parallel to the placement surface 120. When the axial direction of the cyclone 220 is parallel to the placement surface 120, the air outlet direction of the first pipe section 410 is along the radial direction of the cyclone 220.

In the above arrangement, the axial direction of the cyclone 220 may be parallel to the placement surface 120, the axial direction of the driving shaft of the motor 310 is perpendicular to the placement surface 120, at this time, the air outlet direction of the first pipe section 410 may be consistent with the radial direction of the cyclone 220, the extending direction of the second pipe section 420 may be parallel to the placement surface 120, and the air inlet direction of the third pipe section 430 may be consistent with the axial direction of the driving shaft of the motor 310, so that a U-shaped air duct 400 may be formed, and the air outlet direction of the dust cup 210 may be tangential to the inner wall of the dust cup 210, with small air flow resistance.

It should be understood that, in the above arrangement, the axial direction of the cyclone 220 may be perpendicular to the placement surface 120, and the axial direction of the driving shaft of the motor 310 may be parallel to the placement surface 120, where the air outlet direction of the first pipe section 410 may be aligned with the axial direction of the cyclone 220, the extending direction of the second pipe section 420 may be parallel to the placement surface 120, and the air inlet direction of the third pipe section 430 may be aligned with the axial direction of the driving shaft of the motor 310, so that a U-shaped air duct pipe 400 with small wind resistance may be formed to communicate the dust cup 210 with the motor mounting cavity 110.

Referring to fig. 5, in a specific implementation, air release valve assembly 500 includes a communication tube 510 and a control valve 520, a first end of communication tube 510 is communicated with air duct tube 400, and control valve 520 is connected to a second end of communication tube 510 and is configured to control an on-off state of communication tube 510 and an outside of base 130.

Thus, when the pressure in the duct 400 is in the normal range, the control valve 520 may be closed, the gas in the duct 400 cannot flow out through the communication pipe 510, and when the pressure in the duct 400 is large, the control valve 520 may be opened, so that the gas in the duct 400 may be released to the outside of the base 130 through the communication pipe 510, further, the release amount of the gas to the outside of the base 130 may be controlled by adjusting the opening of the control valve 520, so that the pressure in the duct 400 is adjusted to the normal range.

Since the front end of the base 130 along the traveling direction of the acarid-removing cleaner needs to be provided with the dust suction port and the rolling brush, and the rear end of the base 130 along the traveling direction of the acarid-removing cleaner needs to be provided with the handle 150 and the control assembly, the installation space of both ends of the base 130 along the traveling direction of the acarid-removing cleaner is limited, and it is inconvenient to arrange the air release valve assembly 500, and in one possible implementation, the outer side of the base 130 perpendicular to the traveling direction of the acarid-removing cleaner is communicated with the control valve 520.

Thus, the communication pipe 510 is connected to the duct pipe 400 and extends to the control valve 520 in a direction perpendicular to the traveling direction of the acarid-removing cleaner, and the control valve 520 is connected to the inner sidewall of the base 130 perpendicular to the traveling direction of the acarid-removing cleaner and is connected to the outer side of the base 130 perpendicular to the traveling direction of the acarid-removing cleaner, so that when the control valve 520 is opened, gas is released to the outer side of the base 130 to reduce the pressure in the duct pipe 400.

Referring to fig. 2 and 5, in one possible implementation, the housing 100 of the mite-killing dust collector provided by the present application further includes a handle 150, and the handle 150 is connected to the middle portion of the base 130 and extends to the outside of the base 130.

Thus, the user can push the mite-killing dust collector to move on the surface to be cleaned by holding the handle 150 positioned at the rear end of the base 130, and the pushing is more labor-saving.

In one possible implementation, the present application provides an acarid cleaner, where the handle 150 and the direction of travel of the acarid cleaner lie in the same plane.

That is, the motor assembly 300 and the dust cup assembly 200 are positioned at opposite sides of the extending direction of the handle 150, and when the user holds the handle 150 to move the acarid-killing cleaner, the weight of the left and right sides of the hand is uniform, and the lateral deviation is not easy to occur.

The handle 150 may be annular, and the handle 150 may be linear.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
